"Steelers safety Troy Polamalu did not win another Super Bowl ring Sunday, but he rang in $135,000 for veterans, service members and their families through an online auction on Twitter.

The gift is a record for Operation Once in a Lifetime, a Dallas-based charity that helps the military, often with free tickets for travel or entertainment. But the total fell short of expectations -- possibly because of the Super Bowl.

"I'm happy ... but I was hoping for a little bit more," said Patrick M. Sowers, founder and president of Operation Once in a Lifetime.

Sowers said about 30 celebrities, including some Steelers and Dallas Mavericks owner and Mt. Lebanon native Mark Cuban, had said they would help out, but never filled out the paperwork to participate.

In an e-mail, Cuban said he responded and tweeted as asked."
